I can handle the software part. I just want some ideas on how I can change the keys via a cheap and less-effort method. It is not a Peripheral keyboard, just the one integrated with my laptop.
Conclusion: Because numerous people have said it now, I will try to just build a muscle memory of it like I did w/ Qwerty and may not use stickers. Thank you everyone.
I don’t know where you are from, and what laptop you are using, but as others have said: use keyboard stickers. Just search for „colemak dh stickers [your laptop model]“
